Retrospective review of patients with lung cancer presenting emergently.

BACKGROUND

A significant proportion of lung cancer patients receive their diagnosis as part of an emergency presentation (EPs) to emergency departments (EDs).

OBJECTIVES

This study aimed to describe EPs of lung cancer at a safety-net hospital system.

METHODS

We conducted a retrospective analysis of patients with lung cancer at a safety-net ED. EP was defined as a diagnosis of lung cancer due to an acute presentation with symptoms of undiagnosed lung cancer (e.g., cough, hemoptysis, shortness of breath). Non-EPs were the result of either incidental findings (trauma pan-scan) or as part of lung cancer screening.

RESULTS

A total of 333 patient charts were reviewed who had lung cancer. Of those, 248 (74.5%) were defined as having an EP. EPs were more likely stage IV than non-EPs (50.4% vs 32.9%). The percent mortality was higher for EP versus non-EP, 60.0% vs 49.4%. which is driven by a high mortality rate for stage IV EPs (77.5%). Most patients with an EP were seen in the ED (177, 71.4%) as the location of initial visit that had a workup concerning for lung cancer. Most of the EPs were admitted for completion of either their diagnostic work up and/or for symptom management (117, 66.5%). Logistic regression identified significant predictors for an EP including stage IV at diagnosis (OR 2.49, 95% CI 1.39-4.48) and lack of primary care (OR 0.07, 95% CI 0.009-0.53).

CONCLUSION

Most patients with lung cancer present acutely as an EP with advanced stage in a safety-net health care setting. The ED plays an important role in the initial diagnosis of lung cancer and coordinating subsequent cancer care.
